java.lang.RuntimeException: ERROR: Failed to recov

Question

I just had this error message from one of my users. (IE8, Java 1.6.20 ). It is from an applet which receives instructions from Javascript and executes certain processes on the client.

RangeError
java.lang.RuntimeException: ERROR: Failed to recover corrupt cache entry
at com.sun.deploy.cache.CacheEntry.recover
at com.sun.deploy.cache.CacheEntry.getSignerMap
at com.sun.deploy.cache.CachedJarFile.getSignerMap
at com.sun.deploy.cache.CachedJarFile.access$100
....

Any iddeas what could be causing this?

Answer 1

It might be this bug. If so the workaround would appear to be to clear the java cache and try again.

Answer 2

I have experienced this problem at java1.8_0.31 and Only workaround I found so far that put packed jars (pack.gz) to same directory with your jar(s). When tracing the servlet i see that

JnlpDownloadServlet(3): Request: /MyWeb/signed.jnlp
JnlpDownloadServlet(3): User-Agent: JNLP/1.7.0 javaws/11.31.2.13 (<internal>) Java/1.8.0_31

And at client side when tracing log is shown that

Client behaves coming plain jar file as packed and gziped jar. Maybe need to examine HTTP Header to why client do that.
