Error when searching for method callers. Method signature: public Foo(String a, Bar[] b) Message: An internal error occurred during: "Java Search".

BootLoader constants: OS=linux, ARCH=x86, WS=gtk, NL=en_US Command-line arguments: -os linux -ws gtk -arch x86 Before it a warning is issued, but only immediately after Eclipse starts. Message: Skipping builder org.eclipse.ve.java.core.vebuilder for project Fast. Either the builder is missing from the install, or it belongs to a project nature that is missing or disabled. No stack trace. I think I should clean that warning, but I believe that error shouldn't happen anyway. The problem is reproducible and I'm ready to perform additional tests when requested.
Was it a string pattern search (ie. using search dialog) or an element pattern search (ie. using popup-menus)? Would it be possible to make a try with a more recent integration build (I20050506-1600 would be ideal)? Thanks
I tried to search for a method callers using keyboard shortcut (Ctrl+Shift+G), but calling it from menu (Search->References->Workspace) gives the same error.

I got some problem to reproduce this NPE. Perhaps may you try to create a simple test case to help me to get it? The only thing I get is an IllegalArgumentException in Signature.getParameterCount(char[]) when searching reference to Foo(String,Bar[]) in following test case: X.java: public class X { void foo() { new Test().Foo("", null); } } Test.java: public class Test { public Foo(String a, Bar[] b) {} } class Bar {} Note that I get no error when I launch search from Test.java, IAE only happens when I start search from X.java selecting message send Foo... Note also that your method declaration is not a valid as it misses return type... I guess problem surely comes from here... Any other hints on this will be appreciated, I continue to investigate further...
IAE still happens with 3.1 M7 but was a duplicate of bug 94398 (fixed in last nightly build N20050517-0010). So, currently consider your bug as not reproducible and close as WORKSFORME. Please reopen with a more detailed test case if you still get it, thx
