Compilation in JDeveloper 11g may stuck on Appc compilation begin Compiling out of process...
"Sometimes" when you are compiling (or building, or deploying) a J2EE application Jdev may stuck with lines in the Messages window like shown below :
Appc compilation begin
Compiling out of process...
D:\java\jdk1.6.0_45_x64\jre\bin\javaw.exe -Xms128m -Xmx512m -XX:MaxPermSize=128m -Xverify:none -client -classpath D:\java\jdk1.6.0_45_x64\lib\tools.jar;D:\oracle\Middleware_11117\wlserver_10.3\server\lib\weblogic.jar -Dweblogic.jsp.diagnosticWithAbsolutePath=true -Dweblogic.classloader.noJarSigners=true weblogic.appc "@d:\work\cutebank\jdev_user_home\temp\appcCommandList2443558696009904953.txt"
That's not an laptop performance issue. Even if you have compiled the project successfuly 10 times, but on 11th one jdev may hung..
That made me crazy
Solution.
APPC uses the %TMP% dir to store some temporary files and folders.
I found that folder was locked when the jdev begun to behave like described above
To solve the problem just delete the %TMP%\appc_libraries (it may be a little tricky, cuase the folder is locked).
Else you can set another value for %TMP% var.
I prefer to use bat-file to start jdev. Here i can define JDEV_USER_HOME, TMP and others variables.
Hope this helps somebody
Oleg.
