Technic 7+ requires Java 7 and Lion, but there are problems with Java 7 and they're currently working on it.

Thanks for the reply, I'll build the launcher myself with JDK6.

May 11, 2012

I decided not to use the report format because the amount of tests made and results returned. I will include details and my own comment for each test.

Launcher Version: 1.0.1.3

LWJGL Version: 2.8.3

Test 1

Operating System: Mac OS X 10.6.8

Mod Pack: Technic 7.0.1

Java Version: Java 6 SE from Apple (VM: 1.6.0_31-b04)

I opened the launcher on my MacBook which was running Snow Leopard to try play technic but then it caused an error which was obviously caused by not using JDK7.

java.lang.NoSuchMethodError: ic2.api.CropCard.registerBaseSeed(Laan;IIIII)Z

Test 2

Operating System: Mac OS X 10.7.3

Mod Pack: Technic 7.0.1

Java Version: OpenJDK7 (VM: 1.7.0_04-ea-b15)

I then proceeded to play it on my Mac Mini which was running Lion, turned on OpenJDK7(I don't usually use OpenJDK7, the version I installed at that time was a DP version of it.) then opened the launcher. I started Technic but the game window froze on a white screen, I tried the methods supplied in the common problems thread but it failed every time I tried to launch.

[20:28:57] [sEVERE]	Exception in thread &quot;Minecraft main thread&quot;

I peeked at the logs and found out it was a problem with the libraries. I went to the bin/natvies/ folder and found out that there was no such file called "liblwjgl.dylib" but instead I found another file called "liblwjgl.jnilib". At first I suspected the file to be outdated but then after I downloaded the latest lwjgl binaries, I found "liblwjgl.jnilib" but no "liblwjgl.dylib". I found a thread with the same problem and tried the suggested solution: duplicating the file and renaming it to "liblwjgl.dylib". I did but Technic crashed on load, no errors were generated. (Note: the library could have loaded but some unknown reasons caused it to crash)

Test 3

Operating System: Mac OS X 10.7.3

Mod Pack: Technic 7.0.1

Java Version: Java 7 SE (VM: 1.7.0_04-b21) & Java 7 SE (VM: 1.7.0_06-ea-b08)

I found out on the internet that the problem apparently was a missed out feature, not implemented in my version of release.^* I then downloaded the Oracle release of JDK7u4, installed it, then launched Technic, it crashed on load, no errors. This was the same with JDK7u6 DP. I even tried it on a newer build of JDK7u4. (maybe the library did load but somehow caused it to crash.)

Test 4

Operating System: Mac OS X 10.7.3

Mod Pack: Technic 7.0.1

Java Version: OpenJDK8 (VM: 1.8.0-jdk8-b37-20120510)

At this point I was frustrated, but then I read that it was first fixed in JDK8.^** I installed it then it crashed on the launcher. It generated an error report but it said the crash was caused by Java. (I will attach it someone wants it)

Test 5~ (for comparison only)

Operating System: Mac OS X 10.7.3

Mod Pack: VoxelModPack

Java Version: Java 7 SE (VM: 1.7.0_06-ea-b08)

I then proceed to test if other modpacks (voxelmodpack in this case) have the same problem. It does on JDK7.

Java Version: Java 6 SE from Apple (VM: 1.6.0_31-b04)

Tried it with Java 6 and it works, the voxelmodpack does not require JDK7 so it works. (not sure if lwjgl loaded)

Operating System: Mac OS X 10.6.8

Java Version: Java 6 SE from Apple (VM: 1.6.0_31-b04)

Tried it on Snow Leopard, works. (not sure if lwjgl loaded)

Operating System: Mac OS X 10.7.3

Mod Pack: None. Completely vanilla minecraft. (Minecraft launcher)

Java Version: Java 7 SE (VM: 1.7.0_06-ea-b08)

Works without error.

Operating System: Mac OS X 10.7.3

Mod Pack: Technic 6.0.7

Java Version: Java 6 SE from Apple (VM: 1.6.0_31-b04)

Works without error.

Operating System: Mac OS X 10.7.3

Mod Pack: Technic 6.0.7

Java Version: OpenJDK7 (VM: 1.7.0_04-ea-b15)

Freezes on white screen. Cannot load lwjgl.dylib: see error in test 2

Operating System: Mac OS X 10.7.3

Mod Pack: Technic 6.0.7

Java Version: Java 7 SE (VM: 1.7.0_04-b21)

Crashes without error. (not sure if lwjgl loaded)

Please provide solution if anyone is able to launch.^***

Some questions answered for mac users

Will modpacks requiring JDK7 be able to run on Snow Leopard or older?

No. Mac OS X 10.7.3 (Lion)^† is listed as a requirement and it the only supported platform by Oracle. ^‡

Why is the game stuck on a white screen?

The game cannot load the lwjgl libraries. Update Java if using Java 7 or use Java 6.

Why does the game immediately crashes on load? (Before the Mojang logo loads)

This is caused either by a mod, a modpack, lwjgl. No solution or explanation to this currently.

^{* (}^{Technical Discussion}^{) In the}^{JDK7 Mac Port Project Status Page}^{it states (Core Libraries) that in 7u4 you are able to load .jnilib in addition to .dynlib}

^{** (}^{Technical Discussion}^{) Please correct me if I'm wrong}

^{*** I have programming experience, but none for Java. All comments are based on my current knowledge of computers and programming.}

^†^{Purchase Lion}^{64-bit computer required}

^{‡ As stated in the}^{JDK7 Mac OS X Port Wikis}

This is because the Launcher was written against Java 7.

In Java 7 a lot of the Swing elements require parametrization If you want to solve this without removing the parameters and therefore maintain type safety install the java 7 jdk.

Well, there is no JDK 7 release for mac, but there is a DP version which I don't intend to install.

Thanks

Re: Common Problems (And their solutions)

i'm not allowed to change my .cfg files. It's like they are a read only. I just can't select text or delete it or write it. So i can't change my NEI to cheat mode... what do I do? Or what am I doing rong?

Mac users:

Easy way:

[list type=decimal]

[li]Select file and press ?I (Command+I)[/li]

[li]Expand the Sharing & Permissions section[/li]

[li]Click the lock on the bottom right of the window[/li]

[li]Click the plus sign on the bottom left of the window and add yourself[/li]

[li]Change your permission to Read & Write[/li]

Advanced way:

[list type=decimal]

[li]Open terminal[/li]

Type:

sudo chmod 777 /path/to/file(drag and drop file here)

Sorry, can't really help. I just wondered if there was something obvious that had been done in the code, but without poking through the whole thing, I can't say...

Where did you get the source from anyway?

Thanks anyway, I dug through the documentation for Class JComboBox<E> but nothing resolved my problem.

I get this kind of error when I compile the launcher from source with maven.

[ERROR] .../TechnicPack-Spoutcraft-Launcher-d0dbc6f/src/main/java/org/spoutcraft/launcher/gui/LoginForm.java:[130,24] type javax.swing.JComboBox does not take parameters

Using:

[li]maven 3.0.4[/li]
[li]mac os x 10.6/10.7[/li]
[li]JDK 6[/li]
