Description Jaroslav Tulach 2016-05-05 03:16:23 UTC

java.lang.IllegalStateException: Inconsistency: org.netbeans.html.json.spi.Proto@171067df != org.netbeans.html.json.spi.Proto@1b320b74
org.netbeans.html.json.spi.Observers.finishComputing(Observers.java:96)
org.netbeans.html.json.spi.Proto.releaseLock(Proto.java:144)


java.lang.IllegalStateException: Re-entrant attempt to access org.netbeans.html.json.spi.Proto@16dd9d34
org.netbeans.html.json.spi.Observers.verifyUnlocked(Observers.java:76)
org.netbeans.html.json.spi.Proto.verifyUnlocked(Proto.java:137)


Probably caused by global state in Observers that gets mixed up by access from multiple threads.
