I filed issue 1359 (self-profiling hangs when stopped under JDK 11): https://issues.apache.org/jira/browse/NETBEANS-1359
and I wonder if someone could help me figure it out. I traced it by running NetBeans under the debugger: SelfSamplerAction.actionPerformed() creates an org.netbeans.modules.sampler.InternalSampler when self-profiling is started, which creates a SamplesOutputStream. When self-profiling is stopped, Sampler.stop() gets called (superclass method), which calls SamplesOutputStream.close(). This calls writeToStream() on each sample, which fails as soon as toCompositeData() is called (line 178 in SamplesOutputStream). Sampler.java doesn't catch the resulting exception (line 239), so the snapshot save hangs. Some googling brought me to this issue, which has a similar stacktrace: https://issues.apache.org/jira/browse/NETBEANS-882 but I'm over my head at this point. Does anyone understand what's going on with toCompositeData()? 1359 has a repro case, does that help? -- Glenn Holmer (Linux registered user #16682) "After the vintage season came the aftermath -- and Cenbe." --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@netbeans.incubator.apache.org For additional commands, e-mail: dev-h...@netbeans.incubator.apache.org For further information about the NetBeans mailing lists, visit: https://cwiki.apache.org/confluence/display/NETBEANS/Mailing+lists
