When I start to debug eclipse plugin that depends on JDT(core/ui), a
daemon thread(job) that index CompliantUnits also start in the launched
Eclipse, it occupied a lot of memory allocated for JVM but is usefulness
to development, it often cause OutOfMemory as blow:

Exception in thread "Java indexing" java.lang.OutOfMemoryError: Java
heap space
Exception in thread "Java indexing" java.lang.OutOfMemoryError: Java
heap space
at
org.eclipse.jdt.internal.core.index.DiskIndex$IntList.add(Di skIndex.java:73)
at
org.eclipse.jdt.internal.core.index.DiskIndex.copyQueryResul ts(DiskIndex.java:351)
at
org.eclipse.jdt.internal.core.index.DiskIndex.mergeWith(Disk Index.java:522)
at org.eclipse.jdt.internal.core.index.Index.save(Index.java:18 1)
......

Are there some parameters can be configured for Eclipse Application to
stop Indexing?

Thanks in advance!

Java Indexing cannot be configured not to run... This is done like this because
opening a type or any kind of search request definitely needs it.

However, it usually does not report OutOfMemory error and of course should never
do. There's perhaps something in your configuration making the indexing blowing
up and it would be nice if you could open a bug against JDT/Core with all
possible information helping us to understand and allowing us to reproduce
the problem:
- Eclipse build ID
- Other plugins installed
- VM arguments used to launch it
- Workspace info
- etc.

TIA
