When searching for variable declarations in the workspace, in some cases an internal error occurs. The following is shown in the error properties: Session Data: java.version=1.4.2 java.vendor=Sun Microsystems Inc.

>in some cases Is there a pattern or is it random?
Offending line shouldn't fail. if (type.isMember()) { IType enclosingType = type.getDeclaringType(); 840> while (enclosingType.getDeclaringType() != null) { enclosingType = enclosingType.getDeclaringType(); } except on illformed binaries (wrong attributes fooling our decoding support). Klaus - could you provide us with a testcase ?
I will investigate as soon as I get a test case.
Null check has been added. We would like to understand how this happened. Could you please provide a test case and reopen the PR. Thanks.
