Please see https://bugs.eclipse.org/bugs/show_bug.cgi?id=338402 for the master bug. This feature implementation is work in progress, no support exists for code generation yet (deep where is the current failure).
This problem is fixed by the patch posted at https://bugs.eclipse.org/bugs/show_bug.cgi?id=338402#c11 which has been released into the BETA_JAVA7 branch. I have added a slightly modified version of the test from comment#0 into org.eclipse.jdt.core.tests.compiler.regression.TryWithResourcesStatementTest.test029() (see bug 338402 comment 12 for printStackTrace related problems) *** This bug has been marked as a duplicate of bug 338402 ***
Verified.
