[Ikvm-developers] Endless loop in ResourceBundle (LocalObjectCache) due to SoftReference ?

[Christian P. <pro...@op...>]

Hi,

we encounter an endless loop with IKVM when using ResourceBundle.getBundle(string).

Reading the OpenJDK sources for LocalObjectCache shows that there is a "while(value != null)" that seems to loop forever.
The value retrieved from the CacheEntry is stored using a SoftReference.

Can the IKVM SoftReference implementation cause this to happen?
Sadly, as of now, we could not write a testcase that reproduces the bug. But it happens from time to time in our project.

Here is the StackTrace where the application gets stuck:

IKVM.OpenJDK.Core.dll!sun.util.locale.LocaleObjectCache.get(object key = {sun.util.locale.BaseLocale}) + 0xb3 Bytes
IKVM.OpenJDK.Core.dll!java.util.ResourceBundle.Control.getCandidateLocales(string baseName, java.util.Locale locale) + 0x2b Bytes
IKVM.OpenJDK.Core.dll!java.util.ResourceBundle.getBundleImpl() + 0x137 Bytes
IKVM.OpenJDK.Core.dll!java.util.ResourceBundle.getBundle(string baseName) + 0x31 Bytes



Any ideas?


Best regards,

Christian
