After about 1 hour of work with JS file linked in running HTML, it seems that following exception broke all communication with browser and also page in browser went to "He's dead, Jim" ("Aw, snap!") state (standard purple dead page in Chrome).

IDE log shows following exception:

java.lang.Exception
	at org.netbeans.lib.lexer.TokenHierarchyOperation.ensureReadLocked(TokenHierarchyOperation.java:397)
	at org.netbeans.lib.lexer.TokenHierarchyOperation.tokenSequence(TokenHierarchyOperation.java:422)

Comment 1 Petr Hejl 2012-11-28 13:51:59 UTC 
Fixed in web-main 93a5605f157e.
Comment 2 Petr Hejl 2012-11-28 15:05:29 UTC 
I reverted the previous patch 22fb6b71ddd1.

BTW the stacktrace reported in log is not an exception being thrown - it is a warning so it can't break communication.
Comment 3 Vladimir Riha 2012-11-28 15:10:31 UTC 
Sorry, I overlooked it. This was the only "suspicious" thing I saw in the log.
