PostHeaderIcon IntelliJ IDEA: javac: source release 1.6 requires target release 1.6

Case

After my Java project upgrade from “Tiger” to “Mustang”, I tried to launch a “make module” within IntelliJ IDEA. I got this message

javac: source release 1.6 requires target release 1.6

Fix

In IntelliJ IDEA, go to:
File > Settings > Compiler > Java Compiler > remove > Additional command line parameters > remove the parameter -target 1.5

PostHeaderIcon sljava.dll / IntelliJ IDEA / ActivIdentity

Case

The administrators tried to install ActivIdentity on my desktop. Then I rebooted my computer and launched IntelliJ IDEA 8.1.4 as usual.
IDEA froze. I tried to launch former versions (8.0, 7.5.4), with the same result. Then I launched the idea.bat (available in the same folder as the idea.exe), setting echo on, to have a little more logs.

Stacktrace

Caused by: java.lang.UnsatisfiedLinkError: Expecting an absolute path of the library: \Program Files\ActivIdentity\SecureLogin\sljava.dll

Explanation and Fix

I ran other Java applications, such as Eclipse and Mule ESB. The result was the same.

When you look at the stacktrace, you can see that sun.reflect.NativeConstructorAccessorImpl.newInstance0 calls com.actividentity.sso.javasso.awt_swing.JavaSSOHook. This makes me think ActivIdentity intercepts Java calls, even of very low level, and checks them before executing them. I don’t know if compiled code of JRE’s jars is modified, or if some methods are inserted through a mechanism similar to AOP. Anyway, the fact is that ActivIdentity is always called, even though I doubt a lot that original HotSpot was designed to do so…

I tried to uninstall ActivIdentity, this had no effect. I looked in Windows regedit but I found nothing. I tried also to check the value of java.library.path which, for Windows, points to Windows’PATH environment variable.

Therefore, the only solution I found to fix the issue was to changed the JAVA_HOME parameter (more accurately: the parameter IDEA_JDK) from one JDK to another, in my case: from 1.6.0_01 to 1.6.0_18)

PostHeaderIcon svn: OPTIONS request failed on

Case

IntelliJ IDEA 7.x, version control with Subversion.
When I try to update the project, I get the following error:

Error:svn: unknown host myHost svn: OPTIONS request failed on /myProject/trunk/

On another hand, I can update the project thanks to TortoiseSVN. Then, I conclude the server exists and allows updates.

Fix

Firstly I thought of an issue of proxy, hence check your settings if you face the problem. Else:

  • Shutdown IDEA
  • Delete ~/.IntelliJIdea70/system/caches
  • Restart IDEA

PostHeaderIcon Remote debug on Mule 2.2.1

Case

You have to run a standalone Mule 2.2.1 in debug mode. Since Mule is launched in standalone, you have to debug a remote application.

Fix

Nice case

  • Edit the %MULE_HOME%/conf/wrapper.conf
  • Uncomment the line:
    wrapper.java.additional.<n>=-Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=5005
  • Don’t forget to set the parameter <n>

Boring case

In my case (Windows XP SP2, Java 1.5), the Mule refused to start and freezed:

------------------------------------------------------------------------
The JVM is being launched with a debugger enabled and could possibly be
suspended.  To avoid unwanted shutdowns, timeouts will be disabled,
removing the ability to detect and restart frozen JVMs.
------------------------------------------------------------------------
Launching a JVM...
Listening for transport dt_socket at address: 5005
------------------------------------------------------------------------
Startup: Timed out waiting for a signal from the JVM.
The JVM was launched with debug options so this may be because the JVM
is currently suspended by a debugger.  Any future timeouts during this
JVM invocation will be silently ignored.
------------------------------------------------------------------------

The fix this:

  • Download the jar spring-agent here.
  • Move it into %MULE_HOME%/lib/user/
  • Edit the %MULE_HOME%/conf/wrapper.conf
  • add the following block:
  • wrapper.java.additional.3=-javaagent:%MULE_HOME%\lib\user\spring-agent-2.5.3.jar
    wrapper.java.additional.4=-Xdebug
    wrapper.java.additional.5=-Xnoagent
    wrapper.java.additional.6=-Djava.compiler=NONE
    wrapper.java.additional.7=-Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=5005
  • (by the way, even though properties #3 and #5 are inconsistent, don’t mind)
  • launch the Mule
  • In your IDE (Eclipse, NetBeans, IntelliJ IDEA), run debug on localhost:5005

PostHeaderIcon IDEA: “Debug info unavailable”

Error: IntelliJ IDEA does not allow to see the values of local variables. The error message displayed is:  Debug info unavailable.

Fix:

  • open the settings
  • open Compiler tab
  • check Generate debugging info
